针对无线传感器网络能量利用率低和通信质量不高等问题,提出了一种高效低能耗的WSN路由协议.在簇头选取阶段综合考虑了节点的剩余能量、节点的密度、节点的传包成功率等因素,在簇内通信方案上提出了混合路由通信方案,簇间通信在链头选取上考虑了链头自身能量值、链数据传输代价、链头传包成功率以及链头与基站的距离等.并提出了丢包策略.仿真结果表明:该算法能有效均衡节点能耗,提高传输数据包成功率,提高通信质量,延长网络生命周期.
Aiming at the problems of low energy utilization and low communication quality,a low energy efficient routing protocol for WSN is proposed in this paper.In the cluster head election phase,the factors of the residual energy of nodes,the density of nodes and the success rate of packet delivery are took into account.In the stable communication phase,a hybrid routing communication is proposed for the intra-cluster communication,considering node performance,chain data transmission cost and the success rate of packet transmission,a novel chain header selection formula was put forward.What's more,a new packet-discarding scheme is proposed.Simulation under the environment of OMNET+ + proves that compared with LEACH and PEGASIS,the algorithm can increase data receiving rate,improve communication quality and effectively extend the network life cycle.
